BEARING FOR NEC'KS OF ROLLS.

SPECIFIGATION forming part of Letters Patent No. 531,885, dated January1 1895.

gp w fi September 13,1894. Serial No. 522,942.

To aZZ whom it may concern:

Be it known that I, ARTHUR WEsrLEY, a. subject of the Queen of GreatBritain, residing at Dudley, England, have invented a certain new anduseful Improved Bearing for the Necks of Rolls, (for which I haveobtained Letters Patent of Great Britain, No. 8,446, dated May 4, 1892;)and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention consists of a new or improved bearing for the necks ofrolls constructed as hereinafter described.

Bearings of the kind to which my invention refers are commonly calledhot neck bearings and are principally used for supporting the necks oftin plate mill rolls, iron and steel sheet and plate mill rolls andother like rolls.

The object of my invention is so to construct the bearings of the necksof the said rolls as to reduce to a minimum the tendency of the saidnecks to break at the fillet or the curved shoulder of the neck wherethe neck joins the body of the roll.

By the use of bearings of the ordinary kind fine surface cracks areformed at the fillet or curved shoulder of the neck'of the roll inconsequence of the excessive friction at and overheating of that part ofthe roll, and at the aid cracks the necks frequently break or split. Iprevent the production of the said fine surface cracks and therebyreduce to a minimum the breaking of the necks at the fillet or on rvedshoulder by the use of bearings constructed according to my invention.

In a bearing of the ordinary kind the inner end of the bearing situatedunder the fillet or curved shoulder of the neck of the roll is curved ormade convex for the fillet or curved shoulder of the neck of the roll toseat itself closely upon, the whole of the neck of the roll resting onthe bearing, that is, the cylindrical part of the neck rests on thehori- "ontal part of the bearing and the fillet or curved shoulderon theconvex inner end of the hearing.

In making a bearing according to my invention I form a recess at theinner end of the bearing and at that face when the bearing is in usewhich is presented to the fillet or (No model.) Patented in England May4, 1892,11). 8,446.

curved shoulder of the neck of the roll so that the said fillet orcurved shoulder of the neck does not come in contact with the hearing,the whole bearing surface of the neck of the roll being supported on thehorizontal part of the bearing so that overheating at the fillet part ofthe neck of the roll is wholly prevented. The rolls are kept in positionby the snugs and collars bearing againstthe body of the rolls sidewiseas usual.

I prefer to make my improved bearing of bronze the recess situated underthe fillet or curved shoulder of the neck extending nearly across thebearing and the bottom of the recess may either be curved or angular.

In addition to preserving the necks of the rolls, bearings madeaccording to my invention possess the minor advantages that lessfriction being produced at the neck a reduced quantity of lubricant isnecessary and less power is required for driving the rolling mill.

Figure 1 of the accompanying drawings represents in side elevationpartly in longitudinal section, a portion of a cylindrical roll to whicha bottom hot neck bearing constructed according to my invention isapplied, and Fig. 2 represents an end elevation of the same. Fig. 3represents in plan, Fig. t in longitudinal section and Fig. 5 in endelevation, taken at the recessed inner end, my improved hearing detachedfrom the roll.

The same letters of reference indicate the same parts in the severalfigures of the drawings.

a is the cylindrical body of the roll.

I) is the neck of the roll and c the fillet or curved shoulder where theneck joins the body of the roll.

at is the wabbler of the roll.

The bottom bearing of the neck constructed according to my invention ismarked af. The bearing is of the ordinary kind excepting at the innerend or that end which when the bearing is in use is presented to thefillet or curved shoulder c of the roll. At the said inner or fillet endof the bearing I make the recess f which extends nearly from side toside of the said hearing. The shape and position of the said recess fwill be understood by an examination of Fig. l and the separate hearingFig. 3. The said recess f is curved at bottom, but the said recess maybe square or of other angular figure instead of curved as represented inthe drawings.

It will be seen by an examination of Fig. 1

that when the bearing is in use, the recess f at its inner end, issituated under the fillet or curved shoulder a of the neck of the rolland that the said fillet or shoulder does not come in contact with thebearing, the whole bearing surface of the neck of the roll beingsupported on the horizontal seat part c of the bearing, instead of thewhole of the neck resting on the bearing as usual. By the absence at theinner end of the bearing of the usual curved or convex projecting partfor bearing against and supporting the fillet or curved shoulder of theneck of the roll, overheating at the fillet part of the neck of the rollis wholly prevented and the tendency of the said neck to break or splitat the fillet is thereby prevented or reduced to a minimum and as lessfriction is produced. atthe neck, a less quantity of lubricant isrequired as before stated.

sented with respect to a bottom bearing, that is, each side and topbearing has at its inner or fillet end a curved or angular recess whichis situated under the fillet part of the neck of the roll.

The bottom, top and side bearings of the rolls are supported in thehousings in the ordinary way and are kept in position by the ordinaryvappliances which I do not think it necessary either to describe or torepresent.

Having now particularly described and ascertained the nature of myinvention and the manner in which the same is to be performed, I declarethat I claim as my invention- A new or improved bearing for the necks ofrolls provided at itsinner or fillet end with a curved or annular recessextending nearly from side to side of the said inner end so that thefillet or curved shoulder of the neck of the roll does not come incontact at that part with the bearing for the purposes and substantiallyas set forth and shown.
